Specification of Letters Patent.

Application filed April 28, 1909.

Serial No. 492,714.

To all whom it may concern:

Be it known that I, JAMns P. FIELD, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented a new and useful Plow-Reversing Mechanism, of which thefollowing is a specification.

This invention has relation to mechanism for reversing plows, and itconsists in the novel construction and arrangement of its parts, ashereinafter shown and described.

The object of the invention is to provide means located between areversible draft beam and a reversible share or disk, whereby the saidshare or disk is turned from one position into a reversed position as aresult of reversal of the draft beam.

A further object of the invention is to provide a reversing mechanism asstated in which the draft beam is free to swing to reverse in itsinitial movement, and in its final movement engages said plow-reversingmeans, whereby the plow, at the final reversing movement of the draftbeam, is swung to a reverse position.

In the accompanying drawings :-Figure 1 is a top plan view of a plowhaving the reversing means attached thereto. Fig. 2 is a top plan viewof the reversing means, with parts broken away. Fig. 3 is a verticalsectional View of the plow reversing means. Fig. l is a plan view of amodified form of the mechanism. Fig. 5 is a sectional view of the formof mechanism shown in Fig. i.

In the accompanying drawings the reversing means is illustrated asapplied to a disk plow, but the said means may be advantageously appliedto moldboard or share plows, if desired.

The plow consists of a frame 1, which is supported at its ends by furrowwheels 2, and which is provided at an intermediate point with an arcuateguide 3. A ground wheel at is attached to the guide 3 and is adapted totravel upon the surface of the ground in the usual manner. A bracket 5is attached to the frame 1 and is provided with a bearing 6, which isconcentric with the guide 3. A bracket 7 is attached to the outer sideof the frame 1, and the said brackets 5 and 7 are secured in positionupon the frame by the bolts 8, which pass transversely through the sideof the frame 1 and the said brackets. The bracket 7 is provided upon itsupper side with an upstanding pintle 10. A pinion 11 is journaled uponthe pintle and rests upon the upper face of the bracket 7.

A standard 12 is j ournaled in the bearing 6 of the bracket 5, and isprovided at its lower end with a disk 18 or a plowshare, as desired.That portion of the standard 12 which projects above the upper surfaceof the bracket 5 is pyramid-shaped as at 14, and a segment 15 is fixedto the said pyramid-shaped portion of the standard. The segment 15 isprovided at its outerportion with gear teeth 16, which mesh with theteeth of the pinion 11. That portion of the standard 12 which projectsabove the upper surface of the segment 15 is cylindrical as at 1 8 and aflanged collar 18 constitutes on its outward portion 17 a journalconcentric with the axis of the said standard 12. The lower portion ofthe collar 18 rests upon the upper surface of the segment 15 and theupper portion of the said collar 18 is flanged so as to form a washerand a segment plate 17 surrounds the said collar below the said flange.The portion 18 of the standard 12 which projects above the cylindricalportion 18 of the standard is also cylindrical but is threaded at itsupper portion to receive a nut 22 and also a washer 21. Said washer 21bears against the upper faceof the collar 18 and the upper face of thedraft beam 22. A flanged collar 18 surrounds the cylindrical portion 18of the standard 12 and rests upon the upper face of the collar 18contacting with and fitted to the under face of the draft beam 22 andthe under face of the washer 21. The lower portion of the said collar 18being flanged and extended to fit upon the flange portion of the collar18 The outer surface of the collar 18 may be either cylindrical orconical and forms a journal for the bearing formed in the end of thedraft beam 22. Said bearing of said draft beam 22 being made to conformto the said outer surface of the said flanged collar 18 Said outersurface of said flange collar 18 is concentric with the axis of thestandard 12. Said beam 22 may be journaled upon a pintle 6 on the uppersurface of said segment plate 17 and away from the axis of said standard12 or of said segment plate 17 in the manner as illustrated in Figs. land 5 of the drawings. The shoulder on the upper portion of thecylindrical portion 18 of the standard 12 is intended not to engage withthe lower face of the collar 18 but leaves said collar 18 free to pressdown the collar 18 upon the segment 15 so as to hold said segment 15firmly down in fixed relation to the standard 12. The said flangedcollars 18 and 18 may if preferred be made in one piece. The plate 17 isprovided at its outer edge with a depending flange 19 upon the innerface of which is concentrically arranged a set of gear teeth 20, whichmesh with the teeth of the pinion 11 at the opposite side of the saidpinion from that side thereof which meshes with the teeth 16 of thesegment 15. The segment plate 17 is provided upon its upper side and atits edges with upstanding lugs 21.. A draft beam or tongue 22 ispivotally mounted upon the upper end 18 of the standard 12, and isarranged to swing over the surface of the plate 17, and when it arrivesin the vicinity of the edges of the said plate 17 the said beam 22engages the inner faces of the lugs 21. A catch 23 is mounted upon thetongue 22, and when the said tongue is in the vicinity of the end of theguide 8, the said catch enters the perforations 21, pro vided at the endportions of the said guides, whereby the said tongue 22 is temporarilyheld in fixed relation to the guide 3.

From the above description it is obvious that when the draft beam 22 isswung around upon the guide 3 during the act of reversing the plow, inits initial movement, the said draft beam or tongue 22 will leave one ofthe lugs 21, carried by the plate 17, and will move toward the other lug21 upon the said plate. Then the said draft beam 22 nearly completes itsreversal movement it engages that lug 21 to which it is moving and turnsthe said plate 17 during the final reversing movement on the part of thesaid beam. As the said plate 17 swings upon the axis of the standard 12,the teeth 20 carried by the said plate 17 rotate the pinion 11, which,in turn, swings the segment 15 upon the axis of the standard 12.Inasmuch as the said segment 15 is fixed to the standard 12, the saidstandard is turned and the plow 13 carried at the lower portion thereofis swung from one position into a reverse position. As the draftbeam 22is swung in a direction opposite from that above described, the plow 13is moved to a reveirse position from that originally occulec p By thisarrangement it will be observed that in its initial movement the draftbeam 22 does not actuate or move the plate 17, and, consequently, thedraft animals may be directed laterally with relation to the frame 1,and the movement of the draft beam 22 may be gotten well under waybefore the said beam will actuate the plow-reversing means. At the sametime, it will be observed that the parts are so arranged that they maybe located at opposite sides of the frame 1, and, consequently a compactarrangement is effected.

In the form of the invention as illustrated in Figs. a and 5 of thedrawing an upstanding pintle 25 is formed as a part of the plate 17 andthe rear end of the beam 22 is pivoted upon the pintle 25 instead ofupon the upper end of the standard 12 as shown in the other figures ofthe drawing. 1n the modified form it will be seen that the rear end ofthe beam 22 lies between the lug 21 mounted upon the plate 17 and thatas the said beam 22 is swung upon the pintle 25 the parts are operatedin a manner similar to that described in connection with the structurerevealed in Figs. 1, 2, 3 of the drawing.
